In 1970 Topps produced a 720-card set plainly designed with gray borders and blue and yellow backs. This lot is anything but plain as it contains an empty 24 ct. display box graded GAI 7.5 and three unopened Series 1 wax packs graded GAI 9 MINT, 9.5 GEM MINT and GAI 10 PERFECT respectively! Series 1 featured many great cards including #10 Yaz, #21 Vida Blue rookie, #61 NL Batting Leaders with Clemente, and other various leaders cards.
